When all services goes down, telnet to VIP address is trying to connect. CSS don't send TCP RST to the client (it's enabled). tcpdump shows only TCP SYN packets to the CSS, but no response from CSS. It's a bug, or feature? :)

after configuring 'flow tcp-reset-vip-unavailable' in global config mode, CSS send TCP RST to the client.
When is 'flow tcp-reset-vip-unavailable' enabled, is needed to configure "TCP RST client if service unreachable: Enabled" in the content?.
